5. The Waiivera Hot Springs. 

 These springs, now deservedly in such repute, were sampled for the 

 Laboratory here so far back as January 26th, 1873, by Mr. Hardy ; and 

 this sample (a) was about that time analyzed, that is partially so, the 

 result being as follows, stated in grains per gallon : — 

 Organic matter . . 

 Cliloride of sodium 



,, potassium 



Carbonate of lime 



,, magnesia . . 



Sulphate of lime

This water as received was clear, and with a slight alkaline reaction. 

 Since this analysis was made quite a large supply of this water has been 

 presented by His Excellency the Marquis of Normanby, and upon this 

 fb) a fall analysis has been made. It is considerably more saline, as will 

 be seen, than the former sample, so much so that it manifests a distinctly 

 saline taste when applied to the palate. In other respects, however, it 

 possesses similar characters. 



The quantity of fixed matter present in a gallon of it is 219-495 grams, 

 divisible as follows : — 



Chloride of sodium . . . . , . . . 116-715 



,, ,, potassium . . . . . . . . -091

This water is of the same kind as that from Puriri, in the same provin- 

 cial district, but is only of about half its strength. It compares most nearly 

 with the famous continental waters of Vichy in France and Fachingeu in 

 Nassau, both of which are largely used medicinally. 



I find that Dr. J. Carey has given a testimonial to Mr. E. Graham, of 

 Auckland, in favour of this water, which is to the following effect : — " Having
